Xavier Williams rushed for two touchdowns and Mark Gronowski ran for another to help Iowa clobber Wisconsin 37-0 on Saturday night.
Kamari Moulton added 96 yards rushing on 15 carries and a touchdown for the Hawkeyes (4-2, 2-1 Big Ten), who retained possession of the Heartland Trophy and have won four straight against Wisconsin (2-4, 0-3). The Hawkeyes rushed for a season-high 210 yards on 36 carries.
Iowa recorded 17 first-half points off three Badgers turnovers as Wisconsin dropped to 15-17 in Luke Fickell's coaching tenure.
Moulton said the Hawkeyes felt confidence after their first few carries on offense. "You just feel it in the air that it's going to be a big night," Moulton said.
Williams had a 29-yard touchdown run to push Iowa's lead to 30-0 with 10:30 left in the third quar
